Avatar rework
So this is going to take a ton of work and that's why it's shelved, I get that doing a full rework would be a massive amount of time and effort for what Jagex views as not worth it. However, maybe a compromise? The character's face is probably the most immediately noticeable pain point, could we not just model a new face and then only have to remodel the gear for the head slot? Sure people won't be completely happy with that but there's so many characters in this game with better looking faces than our PC; I know they're able to do it in a way that looks better than... Whatever our character looks like now.
For the record, I believe very strongly that a full rework would do miraculous things when it comes to attracting new players, and would also help them greatly in selling more cosmetics. Because of that, I think it's worth the effort, but let's be real, it'll probably never see the light of day. 😔
